Parents should not worry about their teenagers’ delinquent behaviour provided they were well behaved in their earlier childhood.

This is according to researchers behind a study that suggests those who offend throughout their life showed antisocial behaviour from a young age, and perhaps most interestingly, have a different brain structure as adults.

Could this be true?  That your brain is different if you’re a long term offender?

Shane O’Mara is professor of Experimental Brain Research at TCD, and told Mark why he isn't so sure about the research.
